When the valve is positioned such that the bore is aligned in the same direction as the pipeline, it is in open position and fluid can flow through it. Ball valves can be used in a variety of applications and markets, such as transmission and storage, gas processing, industrial, and many more.It explains that ball valves provide reliable leak protection which is especially beneficial in gas applications. Ball valves have low pressure drop and can open and close quickly.
